我如何清除布局的所有的EditText 字段与清除按钮。我有一个注册活动，有大约10个不同的 EditTexts 。我知道我可以去抓住一个参考每个具体然后 set.Text（）;但是，我要寻找一个更具活力的优雅的方式。在所有的项目可能抢布局和循环在那里找的EditText 类型，然后将这些设置为，。不知道该怎么做，但并尝试在网上搜索了它，但没有运气上。任何样品code？

How do I clear all the EditText fields in a layout with a Clear Button. I have a registration Activity that has about 10 different EditTexts. I know I could go and grab a reference to each specifically and then set.Text(""); But I am looking for a more dynamic elegant way. Possibly grab the Layout and loop through all the items in there looking for EditText types and then setting those to "". Not sure how to do that though and tried searching on the web for it but no luck. Any sample code?

推荐答案

由@Pixie答案是伟大的，但我想使它更好。

The answer by @Pixie is great but I would like to make it much better.

此方法工作正常只有当所有的EditText都在单（一个）的布局，但如果有一堆嵌套布局这一code没有处理这些问题。

This method works fine only if all the EditText are in a single(one) layout but when there are bunch of nested layouts this code doesn't deal with them.

抓我的头一段时间，我下面的解决方案作出后：

After scratching my head a while I've made following solution:

private void clearForm(ViewGroup group)
{       
    for (int i = 0, count = group.getChildCount(); i < count; ++i) {
    View view = group.getChildAt(i);
    if (view instanceof EditText) {
        ((EditText)view).setText("");
    }

    if(view instanceof ViewGroup && (((ViewGroup)view).getChildCount() > 0))
        clearForm((ViewGroup)view);
}
}

要使用此方法只调用这个在下列方式：

To use this method just call this in following fashion:

clearForm((ViewGroup) findViewById(R.id.sign_up));

在这里您可以与您的XML文件的根布局的ID替换您R.id.sign_up。

Where you can replace your R.id.sign_up with the id of root layout of your XML file.

我希望这将有助于更多的人喜欢我。

I hope this would help many people as like me.
